A METHOD OF MAKING AN IMPROVED BALLOON CUFF TRACHEOSTOMY TUBE
摘要
There is provided a method of making a balloon having a differential thickness. The method uses a raw tube composed of a thermoplastic polymer which is placed in an asymmetrical mold. The tube is preheated in the mold to a temperature sufficient to soften the material of the tube and inflated with a gas to generally uniformly stretch the material of the tube while allowing the tube to retract lengthwise, thus forming a balloon. The resulting completed balloon has a differential wall thickness wherein the upper region has a thickness of from about 15 to about 30 micrometers and the lower region has a thickness of from about 5 to about 15 micrometers.
